A backpack that everyone can hear

Enough already. Why is it that some people insist on "sharing" their music with the rest of world--whether we like it or not--when today's headphones offer a far superior listening experience? We've seen everything from messenger bags to bowling bags with built-in speakers, and now we have a new backpack that will surely contribute its share of noise pollution.

Scullcandy's "Link" backpack has speakers embedded in its straps for music or--worse, as OhGizmo notes correctly--a cell phone conversation. We've got to get started building that bunker.
